- the presently disclosed subject matter relates generally to surgical instrumentation devices, systems, and related methods, and more specifically to a spinal interbody device, system and method for use in implanting an interbody device between adjacent or separate (i.e. neighboring but not necessarily naturally adjacent) vertebrae.
- first component commonly referred to as a cage
- the cage will then be secured to the vertebrae using bone screws that traverse angled apertures in the cage to attach to upper and lower target vertebrae.
- a second component typically referred to as a plate
- the plate acts to further secure the cage in position and prevents back-out and/or movement or migration of the cage itself.
- the plate is configured to bridge the adjacent vertebrae and attach to the vertebrae via bone screws or similar structure.
- the placement of the first and second components is often performed in a serial fashion which can increase the time required for surgery. Additionally, different insertion instruments have been used for each of the plate and the cage components.
- anterior interbody fusion is a common technique for treating injured, diseased, or otherwise damaged vertebrae and/or disc(s) from an anterior approach.
- the anterior approach allows access to an interbody space with minimal damage to the posterior musculature, while allowing full decompression and/or stabilization of the diseased or damaged disc or vertebrae.
- the cage can include an interbody hollow or open area configured to receive bone graft or other bonding, grafting or regenerative material(s). The regenerative or bonding materials promote fusion of the adjacent vertebrae together.
- a need has been uncovered for a device that has a low profile while providing the above-referenced features.
- a need has been uncovered for a stand alone interbody device intended for use in the cervical region (C3 through C7) of the spine that provides the features of, for example, restoration of disc height, an ability to be fixed to vertebral bodies, and an ability to create opportunities for spinal fusion in cases of degenerative instability, post-discectomy syndrome and post-traumatic instability in the C3-C7 region.

- the at least one flange can be located at a distal end of one of the at least two spring portions such that the at least one flange is moveable towards and away from the longitudinal axis of the shaft under bias of the one of the at least two spring portions.
- the two flanges can each be formed as substantially flat planar extensions substantially perpendicular to a longitudinal axis of the shaft.
- the at least one of the key and mating key, and the at least one of the keyway and mating keyway can be configured such that the plate and cage are freely moveable towards each other when the at least one of the key and mating key is located in the at least one of the keyway and mating keyway, and such that the plate and cage lock with respect to each other when rotated a predetermined amount with respect to each other.
- the plate can be configured as an “S-shaped” structure having a center portion with a longitudinal axis extending between a top end and a bottom end of the center portion.
- the plate can also include a top extension with a top longitudinal axis extending from the top end of the center portion and at an angle away from the longitudinal axis of the center portion, and a bottom extension with a bottom longitudinal axis extending from the bottom end of the center portion and at an angle away from the longitudinal axis of the center portion.

- the key and keyway can be configured such that the plate is prevented from rotational movement relative to the cage during a first linear movement portion of the plate towards the cage, and such that the plate is prevented from linear movement relative to the cage during a second rotational movement portion of the plate relative to the cage.
- a method for use of a spinal interbody device can include providing a spinal cage including at least one of a key and a keyway, and a plate including at least one of a mating key and a mating keyway.
- the method can further include placing the spinal cage between adjacent vertebrae in a spinal column, and inserting one of the key and the mating key into a respective one of the of the keyway and mating keyway by moving at least one of the spinal cage and the plate closer to each other along a substantially linear path and with no relative rotation between the cage and plate while moving along the substantially linear path.
- the method can also include rotating at least one of the spinal cage and the plate with respect to each other such that rotating causes the spinal cage and the plate to be locked together. Once locked together, the user or practitioner can be confident that correct alignment and installation of the device can be achieved during use.

- the key 125 could be permitted to rotate and lock with respect to the keyway 115 at specific predetermined locations along the length of the keyway 115 to allow for an adjustable or selectable locking distance between the cage 10 and plate 20 .
- Such an embodiment could include a plurality of shelves (i.e., lock rails 13 ) that are accessed by openings along the length of the keyway 115 .

Abstract
Description
- 1. Field
- The presently disclosed subject matter relates generally to surgical instrumentation devices, systems, and related methods, and more specifically to a spinal interbody device, system and method for use in implanting an interbody device between adjacent or separate (i.e. neighboring but not necessarily naturally adjacent) vertebrae.
- 2. Description of the Related Art
- In order to stabilize two adjacent or separate vertebrae of the spine, medical professionals will typically place a first component, commonly referred to as a cage, between adjacent target vertebrae. The cage will then be secured to the vertebrae using bone screws that traverse angled apertures in the cage to attach to upper and lower target vertebrae. Sometimes, a second component, typically referred to as a plate, is attached to both the cage and the upper and lower target vertebrae. The plate acts to further secure the cage in position and prevents back-out and/or movement or migration of the cage itself. The plate is configured to bridge the adjacent vertebrae and attach to the vertebrae via bone screws or similar structure. The placement of the first and second components is often performed in a serial fashion which can increase the time required for surgery. Additionally, different insertion instruments have been used for each of the plate and the cage components.
- More specifically, anterior interbody fusion is a common technique for treating injured, diseased, or otherwise damaged vertebrae and/or disc(s) from an anterior approach. The anterior approach allows access to an interbody space with minimal damage to the posterior musculature, while allowing full decompression and/or stabilization of the diseased or damaged disc or vertebrae. The cage can include an interbody hollow or open area configured to receive bone graft or other bonding, grafting or regenerative material(s). The regenerative or bonding materials promote fusion of the adjacent vertebrae together.
- Recently, there have been efforts to integrate the plate and cage components into either a unified or mechanically coupled device. Such a unified device creates efficiency for the practitioner by reducing the number of implantation steps and instruments.
- Accordingly, it may be beneficial to provide a combination cage-plate device in which the attachment structures can be operated with speed and accuracy while also providing consistent locking between the cage and plate components at a precise and relative position. In addition, a need has been uncovered for a device that has a low profile while providing the above-referenced features. In addition to the above, a need has been uncovered for a stand alone interbody device intended for use in the cervical region (C3 through C7) of the spine that provides the features of, for example, restoration of disc height, an ability to be fixed to vertebral bodies, and an ability to create opportunities for spinal fusion in cases of degenerative instability, post-discectomy syndrome and post-traumatic instability in the C3-C7 region.
- According to one aspect of the disclosure, a spinal interbody device can include a cage configured to be inserted between adjacent vertebrae of a spinal column, and a plate. The cage can include at least one aperture and at least one of a key and a keyway. The plate can include at least one of a mating key and a mating keyway, and can be configured to be attached to the cage at an exterior surface of the cage. The plate can include at least one aperture configured to accommodate an attachment structure when the interbody device is in use. One of the key and the mating key can include a shaft extending from a respective one of an anterior surface of the cage and a posterior surface of the plate. The one of the key and the mating key can further include at least one flange extending from a distal end of the shaft. The shaft can be cylindrical and slotless, or can include a slot extending in a direction parallel with a longitudinal axis of the shaft such that the shaft is divided into at least two spring portions. The at least one flange can be located at a distal end of one of the at least two spring portions such that the at least one flange is moveable towards and away from the longitudinal axis of the shaft under bias of the one of the at least two spring portions. The two flanges can each be formed as substantially flat planar extensions substantially perpendicular to a longitudinal axis of the shaft. The at least one of the key and mating key, and the at least one of the keyway and mating keyway, can be configured such that the plate and cage are freely moveable towards each other when the at least one of the key and mating key is located in the at least one of the keyway and mating keyway, and such that the plate and cage lock with respect to each other when rotated a predetermined amount with respect to each other. The plate can be configured as an “S-shaped” structure having a center portion with a longitudinal axis extending between a top end and a bottom end of the center portion. The plate can also include a top extension with a top longitudinal axis extending from the top end of the center portion and at an angle away from the longitudinal axis of the center portion, and a bottom extension with a bottom longitudinal axis extending from the bottom end of the center portion and at an angle away from the longitudinal axis of the center portion.
- According to another aspect of the disclosed subject matter, a spinal interbody system can include a cage configured to be inserted between adjacent vertebrae of a spinal column. The cage can include a keyway extending from an exterior surface of the cage to an interior surface in the cage. The system can also include a plate having a key configured to be attached via the keyway to the cage such the plate can be moved between an unlocked position and a locked position relative to the cage. The key and keyway can be configured such that the plate is prevented from rotational movement relative to the cage during a first linear movement portion of the plate towards the cage, and such that the plate is prevented from linear movement relative to the cage during a second rotational movement portion of the plate relative to the cage.
- According to another aspect of the disclosed subject matter, a method for use of a spinal interbody device can include providing a spinal cage including at least one of a key and a keyway, and a plate including at least one of a mating key and a mating keyway. The method can further include placing the spinal cage between adjacent vertebrae in a spinal column, and inserting one of the key and the mating key into a respective one of the of the keyway and mating keyway by moving at least one of the spinal cage and the plate closer to each other along a substantially linear path and with no relative rotation between the cage and plate while moving along the substantially linear path. The method can also include rotating at least one of the spinal cage and the plate with respect to each other such that rotating causes the spinal cage and the plate to be locked together. Once locked together, the user or practitioner can be confident that correct alignment and installation of the device can be achieved during use.

FIG. 1 is a perspective anterior view of one exemplary embodiment of an interbody device/system 100 made in accordance with principles of the disclosed subject matter. The interbody device/system 100 can include acage 10 and aplate 20 that can be locked into position with respect to each other and molded, machined, printed, or otherwise formed as separate structures. Thecage 10 can be configured as a generally cuboid structure suitable for placement betweenadjacent vertebrae cage 10 is intended to be used in the cervical region (C3 through C7) of the spine. Thecage 10 can also be shaped so as to provide restoration of disc height when placed between thevertebrae plate 20 can be provided for attachment to ananterior surface 11 a of thecage 10. In the locked position, as shown inFIG. 1 , theplate 20 includes anupper aperture 22 a and alower aperture 22 b, each configured to house a bone attachment structure for connecting theplate 20 to each of thevertebrae system 100 can include four separate attachment structures for attachment to thevertebrae vertebra 81 and to the superior surface and anterior surface ofvertebra 82. Thecage 10 andplate 20 can be configured for use in many different medical and surgical procedures, including to create opportunities for spinal fusion in cases of degenerative instability, post-discectomy syndrome, post-traumatic instability, and other diseases, injuries, or malformations in the spine, and particularly in the C3-C7 region. -
FIG. 2A is a perspective posterior view of theplate 20 which, in one embodiment, can be configured as an “S-shaped” structure having acenter portion 21 c located between an upper ortop extension portion 21 a and a lower orbottom extension portion 21 b. Thecentral portion 21 c can include a longitudinal axis extending between thetop extension portion 21 a and thebottom extension portion 21 b. Each of theextension portions upper aperture 22 a can be provided in thetop extension portion 21 a, and alower aperture 22 b can be provided in thebottom extension portion 21 b. Theapertures plate 20 to anterior surfaces of adjacent vertebrae. Thus, theapertures plate 20. For example, a typical bone screw having a rounded or tapered head could be used with theplate 20. However, different types of attachment heads could be used and different types of attachment structures could be used, such as pins, barbs, rivets, trocars, cements, and other adhesive or attachment structure. - A key 25 can be located at the
center portion 21 c of theplate 20. The key 25 can be integrally formed with theposterior surface 29 p of theplate 20 such that theentire plate 20 is constructed from a continuous (same) material. Alternatively, the key 25 can be separately formed and attached to theposterior surface 29 p of theplate 20 by an attachment structure or mechanism, such as screw threading, clip, separate attachment structures, welding, or other attachment structure or mechanism. In this embodiment, the key 25 is integrally formed and extends from a central axis of theplate 20. Aboss 25 g is formed at the base of the key 25 where the key 25 extends from theposterior surface 29 p of theplate 20. The key 25 can include ashaft 25 s with a longitudinal axis extending substantially (i.e., totally or almost totally) perpendicular with respect to theposterior surface 29 p of theplate 20. - The
shaft 25 s of the key 25 can include a plurality ofslots 24 that extend parallel with the longitudinal axis of theshaft 25 s such that the shaft is divided into a plurality ofkey sub-sections 25 c. Thus, each of thekey subsections 25 c can be moved relative to each other under relative bias. When moved, thekey subsections 25 c will be biased back towards a neutral position. - At least one
flange 25 a can be located at a distal end of theshaft 25 s. Theflange 25 a is shown as being shaped as a substantially semi-circular lobe. However, theflange 25 a can take on many different shapes that can perform the appropriate keyway function depending on application, design choice, or other criteria. For example, theflange 25 a can be rectangular, square, triangular, or other polygonal shape. In addition, theflange 25 a can be curved in a semi-oval shape, non-symmetrical shape, symmetrical curved free form shape, or other shape. If more than oneflange 25 a is located at the distal end ofshaft 25 s, each of theflanges 25 a can have the same or different shapes. If theflanges 25 a are differently shaped, the user may be required to orient theplate 20 with respect to the cage in only one relative attachment position, thus assisting in consistent and repeatable quick attachment between the two structures when specific orientation is desired. Further, theflange 25 a can be a three dimensional structure such as a hemisphere or other dimple or button shaped structure. Additionally, theflange 25 a can be oriented and configured to include opposing flat surfaces that are either substantially perpendicular to a longitudinal axis of the key, or substantially parallel with the longitudinal axis of the key, or other orientation. -
FIG. 2B shows a specific exemplary embodiment of aplate 20 in which the key 25 includes afirst flange 25 a′ that is formed in a non-symmetrical shape and is different from a second directly opposingflange 25 a″ which is formed in a substantially rectangular shape. Theshaft 25 s′ of the key 25 is a solid shaft with no slits running parallel with the longitudinal or central axis of the key 25. -
FIG. 2C shows yet another specific exemplary embodiment of aplate 20 in which the key 25 includes afirst flange 25 a″ which is formed in a substantially rectangular shape. Theshaft 25 s of the key 25 can be a solid shaft with no slits running parallel with the longitudinal or central axis of the key 25. Asecond flange 25 a′″ can be formed as a pyramidal shape that is polygonal (triangular) as viewed from above (along the longitudinal or central axis of the key 25) and extends a substantial distance above and below the otherwise flat top surface of the key 25 and lower flat surface offlange 25 a″. Thus, theflange 25 a′″ provides an example of a flange that has three-dimensional characteristics. -
FIG. 3A is a front view of the anterior surface of thecage 10. In this view, anexemplary keyway 15 is shown as including a substantially (i.e., totally or almost totally) circular cylindrical aperture extending from the exterior anterior surface of thecage 10 to an interior portion of thecage 10. Thekeyway 15 can be located in a recess, such assquare recess 16, located in theanterior face 11 a of thecage 10. The recess can be configured to mate with a locking structure of theinsertion tool 71 and can also be configured to mate with a structure, such asboss 25 g, in theplate 20 to positively position theplate 20 relative to thecage 10 when they are joined together. - The
keyway 15 can include at least one flange opening 15 a extending from a periphery of the cylindrical aperture. Theflange opening 15 a can run along an interior face of thekeyway 15 and parallel with the longitudinal axis of the cylindrical aperture. The cross-section shape of the flange opening 15 a as viewed from a longitudinal/central/symmetrical axis of the keyway 15 (as viewed inFIG. 3A ) can be shaped and dimensioned to match the shape and dimensions of one of thekey flanges 25 a. Thus, thekeyway 15 and key flange opening 15 a will allow the key 25 andkey flanges 25 a to pass therethrough. In addition, ifkeyway 15 and key flange opening 15 a are constructed with appropriate tolerances with respect to thekey flange 25 a and key 25, thekeyway 15 can provide some amount of support and guidance for the key 25 as it passes along thekeyway 15. - Similar to the description above related to the many different shapes and orientations possible for constructing the
flange portion 25 a, the key flange opening(s) 15 a can also be formed in many different shapes, sizes, dimensions and orientations. For example, the key flange opening(s) 15 a can be rectangular, square, triangular, or other polygonal shape. In addition, the key flange opening(s) 15 a can be curved in a semi-oval shape, non-symmetrical shape, symmetrical curved free form shape, or other shape. If more than one key flange opening 15 a is located in thekeyway 15, each of thekey flange openings 15 a can have the same or different general shape. If thekey flange openings 15 a are differently shaped, the user may be required to orient theplate 20 with respect to thecage 10 in only one relative position for attachment, thus assisting in consistent and repeatable quick attachment between the two structures when specific orientation is desired. Further, the key flange opening(s) 15 a can be constructed such that it selectively allows different size orshape flange portions 25 a to pass through, while not permitting other shapedflange portions 25 a. In other words, various combinations offlange openings 15 a andflange portions 25 a can be designed to work together even though they do not perfectly match with respect to specific shape or size, etc. However, certain other combinations offlange openings 15 a andflange portions 25 a can be designed to not work together to ensure thatcertain plates 20 are never matched withcertain cages 10. -
FIG. 3B is a front view of the anterior surface of anotherexemplary cage 10 in which keyway 15 includes a first non-symmetrical flange opening 15 a′ that is directly opposed to a substantially rectangular flange opening 15 a″. Thus, it would be possible for the plate shown inFIG. 2B to mate with the cage shown inFIG. 3B . -
FIG. 3C is a front view of the anterior surface of anotherexemplary cage 10 in which keyway 15 includes a first substantially rectangular flange opening 15 a″. In addition, thekeyway 15 includes a somewhat triangular flange opening 15 a′″. The depth of the flange opening 15 a′″ can differ from the depth of flange opening 15 a″ in order to accommodate a three dimensional flange therein. In addition, the depth of the flange opening 15 a′″ can be different from a depth of the flange opening 15 a″ in order to provide different locking characteristics when theplate 20 andcage 10 are rotated with respect to each other with the key 25 fit into thekeyway 15. It may be possible for the plate shown inFIG. 2C to mate with the cage shown inFIG. 3C depending on the depth of theflange openings 15 a″ and 15 a′″. -
FIG. 3D is a perspective anterior view of thecage 10 which can include amain cage aperture 12 designed to be filled with a bone regenerative material and/or biocompatible adhesive material that facilitates the fusing of the upper andlower vertebrae superior surface 11 c′ of thecage 10 can include themain cage aperture 12 that extends through to theinferior surface 11 b of thecage 10. In addition, one or both of thesuperior surface 11 c andinferior surface 11 b can include locking projections, such asspikes 18 a orgrooves 18 b. The lockingprojections cage 10 orplate 20 with respect to thevertebrae cage 10 can also include medial and lateral openings that extend from themedial face 11 e andlateral face 11 f to themain cage aperture 12. These openings be designated for bone or other tissue in growth, can provide further anchor locations, or can be openings that simply reduce the overall weight of the device. - The locking projections, such as
spikes 18 a orgrooves 18 b, can be integral with thecage 10 or can be structure(s) that are separately attached to thecage 10. The lockingprojections main cage aperture 12 such that the cage is prevented from movement relative to the adjacent vertebrae to which thecage 10 is attached. Thus, thecage 10 can promote stability between adjacent vertebrae and can also promote bone ingrowth into thecage 10 including themain aperture 12. - As shown in
FIG. 3A , aleft aperture 11 x and aright aperture 11 y can be provided in theanterior face 11 a of thecage 10. Theapertures anterior face 11 a to thesuperior face 11 c andinferior face 11 b of thecage 10, respectively. Theapertures screw 51 to fit neatly within eachaperture screw 51 extending outside of a plane containing theanterior surface 11 a). Thus, ascrew 51 can be inserted throughleft aperture 11 x and intovertebra 81 and anotherscrew 51 can be inserted throughright aperture 11 y and intovertebra 82 to lock thecage 10 with respect tovertebrae apertures apertures cage 10. For example, atypical bone screw 51 having a rounded or tapered head could be used with thecage 10. However, different types of attachment heads could be used, and different types of attachment structures could be used, such as pins, barbs, rivets, trocars, cements, and other adhesive or attachment structures. -
FIG. 4A is a perspective view of thecage 10 andplate 20 in a detached position just prior to engagement and attachment.FIG. 4B shows aninstallation tool 71 that can be used in conjunction with placing one or both of thecage 10 andplate 20 in position relative tovertebrae 81, 82 (or relative to each other). Thetool 71 can have a threadedend 73, and theplate 20 can includemating threads 27, such as M3 threads, located on an interior surface of a central opening that extends from an anterior surface of theplate 20 and through the key 25. Thus, theinsertion tool 71 can lock onto theplate 20 via these mating threads. An installationupper aperture 23 a and an installationlower aperture 23 b can be provided in theplate 20 on respective sides of the key 25. Each of theapertures prongs insertion tool 71 during installation of theplate 20 onto thecage 10, or during installation of both theplate 20 andcage 10 into an intervertebral space. Thus, the plate 20 (or theplate 20 and cage 10) can be rotated together with theinsertion tool 71. - The installation tool 71 (or a different installation tool) can also be used to attach solely to the
cage 10 and facilitate placement of thecage 10 in an intervertebral space. In order to achieve attachment between theinstallation tool 71 andcage 10, the keyway can includethreads 17, such as M3 threads, that mate with threads on theinstallation tool 71. A recess, such assquare recess 16, can be provided in theanterior surface 11 a of thecage 10 such that the recess mates with a similarly shaped portion of theinsertion tool 71 when the insertion tool threads are locked onto thethreads 17 of the cage. Thus, similar to theinstallation apertures 23 a, b of theplate 20, the recess (square recess 16) will lock thetool 71 with thecage 10 such that no relative rotation can take place between thetool 71 andcage 10. -
FIG. 5A-C depict sequential stages of an exemplary method for attaching theplate 20 to thecage 10. InFIG. 5A , theanterior surface 29 a of aplate 20 is shown, with theplate 20 being oriented with respect to thecage 10 in such a way that the key 25 can freely slide along the central or longitudinal axis of thekeyway 15. Thus, thecage 10 andplate 20 can move freely towards (or away from) each other inFIG. 5A , but are prevented from rotation with respect to each other while the key 25 is located in thekeyway 15. Rotation can be prevented until the key 25 reaches a predetermined position within thekeyway 15.FIG. 5B depicts theplate 20 andcage 10 when they are located at such a predetermined “motion transition” position. In this position, thekey flanges 25 a are located just outside of thekeyway flange openings 15 a and adjacent alock rail 13. The key 25 (and plate 20) can now begin to rotate with respect to the keyway 15 (and cage 10) at this position, but are prevented from translating along or with respect to the longitudinal or central axis opening of thekeyway 15. Specifically, theplate 20 can be rotated in a counterclockwise direction (as viewed inFIG. 5B ) such that thekey flanges 25 a start to ride along and on top of thelock rail 13 located withinkeyway 15. Thelock rail 13 prevents thekey flanges 25 a (and plate 20) from pulling back out of thekeyway 15 after this rotation motion has begun. Likewise, the posterior surface of theplate 20 is in contact with the anterior surface of thecage 10 to limit further axial or translation movement between thecage 10 and plate 20 (i.e., to prevent further movement in the linear attachment direction between thecage 10 and plate 20). - Between
FIGS. 5B and 5C , theplate 20 is rotated with respect to thecage 10 to a final locked position as shown inFIG. 5C . In this final locked position, theplate 20 can be configured such that a substantial portion of theattachment apertures plate 20. Thus, thescrews 51 are prevented from backing out of the cage 10 (and prevented from backing out of thevertebrae 81, 82) when theplate 20 is located in the final locked position relative to thecage 10. The final locked position can be defined by ahard stop structure 19 a located at a specific position along thelock rail 13. -
FIG. 6 is a close-up rear posterior/inferior perspective view of thecage 10 andplate 20 in a final locked position. Once theplate 20 has been rotated though a specific arc (in this case, approximately 90 degrees) theflange portions 25 a can be configured to engage with (and be locked adjacent) the hard stop structure(s) 19 a. The hard stop structure(s) 19 a can be configured as an outdent or other protruding structure that extends from an interior wall into thekeyway 25. For example, thehard stop structure 19 a can be formed as a type of ramp such that an outermost peripheral portion of the flange portion(s) 25 a slowly engages the ramp during rotation until frictional forces prevent further rotation between the flange portion(s) 25 a and the hard stop(s) 19 a (ramps). Alternatively, the ramp(s) can include an indent which the flange portion(s) 25 a snap into upon arrival. Such structure could provide both an audible and tactile sensation to the user to indicate that the final locked position has been achieved. In order to define the amount of rotation required to arrive at the locked position, thehard stop 19 a can be spaced a predetermined distance from the at least one flange opening 15 a. Thehard stop 19 a can be configured to lock theplate 20 with respect to thecage 10 such that the user or practitioner is confident that the positional relationship between thecage 10 andplate 20 is accurate and ready for installation in between the vertebrae to provide the above-stated benefits associated with the procedure (e.g., stabilization of vertebrae, proper spacing between vertebrae, etc.) -
FIG. 7 is a perspective posterior view of another embodiment of a cage and plate device/system made in accordance with principles of the disclosed subject matter. In this embodiment,flange portions 125 a are oriented such that they extend at an angle relative to a longitudinal axis LA of theplate 20 when viewed from a front of theplate 20. This angle is different from the angle at whichflange portions 25 a are oriented with respect to theplate 20 of, for example,FIG. 2A , where theflanges 25 a extend at an angle of zero degrees with respect to the longitudinal axis of theplate 20. Thekeyway flange openings 115 a, as shown inFIG. 7 , can be oriented such that they extend in a direction substantially parallel with the a central axis CA of the cage aperture 12 (i.e., substantially vertically). - Installation indents 123 a, 123 b can be formed in a front anterior surface of the
plate 20 on either side of thekeyway 125 such that an installation tool can be threaded into an internal surface ofkeyway 125 while projections on the installation tool lock intoindents plate 20 and insertion tool can be prevented during installation due to the projections on the installation tool locking intoindents indents plate 20, projection structures that mate with the projections on the installation tool, etc. -
FIG. 8A is a perspective posterior view of theplate 20 ofFIG. 7 which shows the angular relationship between the extension direction of theflanges 125 a and the longitudinal axis LA ofplate 20. It should be noted that theplate 20 itself can also be arched such that the longitudinal axis LA curves inward towards the key 125 at the top and bottom of theplate 20 in order to facilitate mating with a bone or tissue surface. Theshaft 125 s of the key 125 can also be split such that theflanges 125 a can move relative to each other while being biased to return to an original position under a predetermined biasing force. -
FIG. 8B is a front anterior view of thecage 10 ofFIG. 7 in which akeyway 115 is located within asquare indent 116 in an exterior surface of thecage 10. Thekeyway 115 can include diametricallyopposed flange openings 115 a that extend in an upward and downward direction, respectively. Moreover, theflange openings 115 a can extend in a direction that is substantially parallel with the central axis CA of themain aperture 12 of thecage 10. The relative positioning and structural configuration of both thekeyway 115 and key 125 allow thecage 10 andplate 20 to lock together at different positional relationships as compared to the positional relationship of thecage 10 andplate 20 shown inFIG. 1 . The different lock positions, as well as the different locking motions, allow for creative and efficient arrangement of thecage 10 andplate 20 system along a spinal column. Specifically, when a plurality ofcage 10 andplate 20 sets are used adjacent each other to stabilize a portion of a spinal column, the spacing betweencage 10 andplate 20 sets can be minimal. Thus, because the orientation and relative configuration of theplate 20 relative to thecage 10 is different in these tworespective plate 20 andcage 10 sets (i.e., the set ofFIG. 1 and the set ofFIG. 7 ), in certain applications, eachplate 20 will be able to be oriented in a stacked manner along a spinal column (for example as shown onFIG. 8C ). Other features that can enhance efficiency of spacing betweendifferent cage 10 andplate 20 sets include different physical sizes of theplate 20 and different orientations of attachment apertures, etc. - In
FIG. 8C , when stacked, theadjacent cages 10 can be oriented in a similar manner with respect to theadjacent vertebrae plates 20 can be locked at different rotational amounts with respect to eachrespective cage 10 such that theplates 20 do not contact each other when in a stacked configuration, and such that different structural configurations foradjacent vertebrae -
FIG. 9A is a front anterior view of thecage 10 andplate 20 ofFIG. 7 in an initial attachment position. As shown, the longitudinal axis of theplate 20 is at a substantially (exactly or approximately) 45 degree angle with respect to the central axis CA of themain aperture 12 of thecage 10. In this orientation, theflange portions 125 a of the key 125 can extend upward and downward (vertically) from a substantially cylindrical main shaft of the key 125 such that theflange portions 125 a can be inserted into thekeyway 115 in thecage 10 Likewise, theflange openings 115 a of thecage 10 can also extend upward and downward (vertically) in order to mate with theflange portions 125 a to allow the above-described mating. In the position shown inFIG. 9A , the geometry of thekeyway 115 and the key 125 can be configured such that linear movement between thecage 10 andplate 20 is permitted in a direction toward and away from each other (into and out of the plane of the drawing), while relative rotation between thecage 10 andplate 20 is prevented between the initial position and end position (i.e., relative rotation is prevented when the key 125 initially engages thekeyway 115 and throughout the insertion motion until the key 125 is fully inserted into the keyway 115). - Alternatively, the key 125 could be permitted to rotate and lock with respect to the
keyway 115 at specific predetermined locations along the length of thekeyway 115 to allow for an adjustable or selectable locking distance between thecage 10 andplate 20. Such an embodiment could include a plurality of shelves (i.e., lock rails 13) that are accessed by openings along the length of thekeyway 115. The key 125 would be rotatable at each of the openings to ride along a separate shelf which, once engaged by theflange portions 125 a, could be configured to prevent linear motion between thecage 10 andplate 20 towards and/or away from each other. Each of these shelves or lockrails 13 could include a hard stop structure that would lock thecage 10 with respect to theplate 20 at a predetermined rotational position with respect to each other upon reaching that hard stop structure. -
FIG. 9B is a front anterior view of the cage and plate ofFIG. 7 in a counterclockwise farthest locked position. After the key 125 ofcage 10 is linearly inserted to a position in thekeyway 115 at which alock rail 13 is located, thecage 10 can then be rotated to a farthest locked position at which point a hard stop can be provided to prevent further relative rotation. In the embodiment shown inFIG. 9B , the farthest locked position is located substantially 90 degrees from the initial insertion position and rotated counterclockwise as viewed from an anterior position along a central axis of thekeyway 115. Alock rail 13 or shelf can be positioned such that theplate 20 can only be rotated counterclockwise with respect to thecage 10 after the key 125 reaches a predetermined position within thekeyway 115. However, it is contemplated that thekeyway 115 and lockrail 13 can be configured to also allow for optional clockwise rotation. In addition, a final locked position need not be the farthest locked position as defined above. For example, once theplate 20 andcage 10 are attached viakey 125 andkeyway 115, slight rotation of the two components (cage 10 andplate 20, relative to each other) will cause the components to become initially locked together. The user can then choose the final plate position between a range of positions between this initial locked position and the furthest locked position, depending on the particular application and other variables such as size and shape of bone and surrounding tissue, etc. -
FIG. 9C is a front anterior view of the cage and plate ofFIG. 7 in a clockwise farthest locked position. After the key 125 ofcage 10 is linearly inserted to a position in thekeyway 115 at which alock rail 13 is located, thecage 10 can then be rotated clockwise to a farthest locked position. In the embodiment shown inFIG. 9C , the farthest locked position is located substantially 90 degrees from the initial insertion position and rotated clockwise as viewed from an anterior position along a central axis of thekeyway 115. Alock rail 13 or shelf can be positioned such that theplate 10 can only be rotated clockwise with respect to thecage 10 after the key 125 reaches a predetermined position within thekeyway 115. However, it is contemplated that thekeyway 115 and lockrail 13 can be configured to also allow for optional counterclockwise rotation. Furthermore, thelock rail 13 can be configured such that counterclockwise rotation is only permitted when the key 125 is located at one or more linear locations along thekeyway 115, and clockwise rotation is only permitted when the key 125 is located at one or more different linear locations along thekeyway 115. -
FIG. 10 is a partial posterior rear view of the cage and plate ofFIG. 7 in the initial attachment position. The key 125 is shown fitting withinkeyway 115 such that thecage 10 andplate 20 can move linearly towards and away from one another (into and out of the sheet of the drawing figure). Once the key 125 is located at a fully engaged position, theflange portions 125 a can then rotate over and onto thelock rail 13. Once rotation begins, thecage 10 andplate 20 can be prevented from moving linearly towards and away from one another (into and out of the sheet of the drawing figure) by interaction of theflange portions 125 a on the lock rail 13 (and interaction of a surface of theplate 20 with an exterior surface of the cage 10). A hard stop structure, such as protrudingramp 19, can be provided along thelock rail 13 such that when aflange portion 125 a is rotated into and contacts the hard stop structure, the protrudingramp 19 will frictionally engage with theflange portion 125 a and prevent further rotational movement and/or lock theflange portion 125 a (and key 125) in place with respect to thekeyway 115 such that thecage 10 is locked in place with respect to theplate 20. - While certain embodiments of the invention are described above, it should be understood that the invention can be embodied and configured in many different ways without departing from the spirit and scope of the invention. For example, as explained above, the geometry of the flange portion(s) 25 a and the keyway opening(s) 15 a can vary considerably and remain within the contemplated scope of the present subject matter. Likewise, the
keyway 15 itself and key 25 can be differently sized or shaped or oriented. Theflange portions 25 a could be located at an intermediate portion of a longitudinal axis of the key to allow for further structure to be placed at a distal end of the key 25. - The material from which both the
plate 20 andcage 10 are made can vary considerably. For example, each of theplate 20 andcage 10 can be made from stainless steel, titanium, aluminum, alloys, ceramics, carbon fiber, PEEK, plastics, bone, and other biocompatible and/or bone regenerative materials naturally occurring or man-made materials. Each of the structures can also be supplemented with bio-compatible and/or bone/tissue regenerative materials, such as meshes or platings that can be attached or formed on surfaces of thecage 10 orplate 20. Thecage 10 andplate 20 can be made from the same or different material depending on particular applications and desires of a user. The specific overall shape of thecage 10 andplate 20 can also vary widely in accordance with patient needs or user preference. The shapes can also be predetermined for a specific patient through the use of pre-operative imaging and subsequent computer modeling of each of thecage 10 andplate 20. - With respect to the various methods that can be used to practice the presently disclosed subject matter, it is contemplated that the specific steps can be executed sequentially, but can also be executed simultaneously and/or in reverse or other orders. Relative rotation between the
cage 20 andplate 10 can be in either rotational direction without departing from the scope of the disclosed subject matter. In addition, the disposition of the key and keyway can be reversed (i.e., theplate 20 can include a keyway while thecage 10 includes a key). The keyway is shown as forming a slot that is disposed at a 45 degree angle with respect to the inferior and superior surfaces of thecage 10 in order to provide efficient spacing for the keyway and key. However, it is contemplated that the location of the flange openings can form a slot at different angles other than 45 degrees with respect to the inferior and superior surfaces. In addition, the flange opening may not necessarily be diametrically opposed to each other so as not to form a slot like opening for the flanges. Other insertion tools could be used with thecage 10 andplate 20, including an insertion tool that does not require threads and matching threads for attachment and insertion of the various structures. For example, the insertion tool can be formed as a clamp or can include a rivet, cam, trocar, pin, or other locking structure for attaching to theplate 20 and/orcage 10. - The number of flange portions and flange openings need not be equal. There could be more flange openings than flange portions such that a user can choose from a number of potential starting positions of relative rotation between the
cage 10 andplate 20. In addition, there can be a single or multiple hard stop structures. Thehard stop structures lock rail 13. However, the hard stop structures could be separate structures that are attached to thecage 10 by a suitable attaching structure or material. The hard stop structures could also be located away from thelock rail 13. In particular, the hard stop structures could be located on either anterior or posterior surfaces of thecage 10 andplate 20 that mate with each other, respectively. For example, dimple(s) could be provided on a posterior surface of theplate 20 while mating protrusions could be formed or attached to the anterior surface of thecage 10. Various other structures, such as ramps, cams, lock pins, etc., can be used as a hard stop structure to rotationally lock thecage 10 with respect to theplate 20. - The cage and plate as depicted can be used for the cervical region of the spinal column. However, it is contemplated that the disclosed subject matter could be employed in other areas of the spinal column. For example, if the cage and plate are enlarged and shaped slightly differently, the device, system and method can be used in the lumbar and/or thoracic regions of the spine. The device, system and method can be used in vivo on human beings but can also be used for teaching purposes in cadavers, and plastic or other model spinal columns. In addition, the device, system and method can be used in veterinarian practices for invertebrate animals.
- It should be noted that any specific feature from any or each of the disclosed or contemplated embodiments can be used in conjunction with or swapped with like features of other embodiments. For example, the installation upper indent/
aperture 23 a and installation lower indent/aperture 23 b can be added or removed from any of the embodiments. In addition, the specific geometrical shape for various structures, including theflanges apertures 22 a, etc., can be interchanged between any of the embodiments. The key 25, 125 can be solid or slotted in any of the embodiments, and can also be shaped variously in the different embodiments depending on user preference or particular application parameters. - While the subject matter has been described in detail with reference to exemplary embodiments thereof, it will be apparent to one skilled in the art that various changes can be made, and equivalents employed, without departing from the scope of the invention. All related art references discussed in the above Description of the Related Art section are hereby incorporated by reference in their entirety.
